The coral symbiotic algae zooxanthellae is often expelled from the host as the host coral is under physiological stress, causing the coral to turn completely white. Such coral bleaching events are occurring more frequently with the increase in the global warming, ocean acidification and increased le...

산호 탈색현상은 어떻게 나뉘는가? | 산호 탈색현상은 광범위한 지역에서 발생하는 대규모 탈색현상과 특정 지역에서 국지적으로 발생하는 소규모 탈색현상으로 나눌 수 있다. 대규모 탈색현상은 기후 변화와 엘니뇨에 의한 수온 상승으로 발생하며(Gates et al. | |
산호초 탈색현상이 가져오는 손실은 무엇인가? | 산호초 탈색현상(coral bleaching)은 돌산호(Scleractinian Coral)의 탄산칼슘 외골격이 하얗게 탈색되어 발생한다. 그 원인은 산호 조직 내 공생하면서 산호에게 영양 공급원 역할을 하는 갈색공생조류(zooxanthellae)가 이탈하기 때문에 나타나고, 대량 폐사로 이어질 가능성이 크기 때문에 해양 생물 서식지를 제공하는 산호초 생태계에 치명적이다(Hoegh-Guldberg 1999). 이 현상은 전세계적으로 발생하여 산호초 생태계에 의존하는 어업, 관광업 등 인류에게도 커다란 경제적 손실을 가져 오고 있다(Costanza et al. 1997; Heck et al. 2003). | |
